How consistently do ensemble prediction systems represent the growth of atmospheric uncertainty?

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Spread‐based diagnostics calculated for 12 ensemble prediction systems are compared to understand the consistency with which they represent atmospheric uncertainty growth. Good correlation between all these systems is found in the extratropics for a lead time range from 48 hr to between 96 hr and 192 hr.

A new method to identify and explain sources of precipitation modification, illustrated for the western Netherlands

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study develops a method to identify the source areas of precipitation events, as illustrated for the western part of the Netherlands. Radar‐based precipitation data are traced back to their source areas and machine‐learning techniques are used to identify hypothesized causes: urban heat, surface roughness, and air pollution. We find that urban and

An evaluation of cloud microphysical parameterization schemes at 1.667 km resolution in the simulation of super cyclone Amphan and extremely severe cyclonic storm Phailin

open access: yesGeomatics, Natural Hazards & Risk
Present work was an attempt to analyze the performance of the Advanced Research version of WRF (ARW) model in simulation of a super-cyclone Amphan and an Extremely Severe Cyclonic Storm Phailin over Bay of Bengal using nine different cloud microphysical ...

The climate of the Waikato Basin [PDF]

open access: yes, 1967
The topography of the Waikato Valley and its position in relation to the large-scale weather system give it warm humid summers, mild winters and a moderate rainfall with a winter maximum.

A multimodel intercomparison study of variable‐resolution global models with grid refinement over the Arctic and Antarctic

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We document the protocol and first results from the first ever coordinated multimodel variable‐resolution experiment set with refinement over the polar regions. We find that the refinement generally yields model‐dependent effects. The most consistent improvement is an amelioration of the upper‐level cold bias in the polar regions that translates into ...

Modulation of wind drag by tidal currents in an embayment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)

Strong enhancement of chlorophyll a concentration by a weak typhoon

open access: yes, 2010
Recent studies demonstrate that chlorophyll a (chl a) concentrations in the surface ocean can be significantly enhanced due to typhoons. The present study investigated chl a concentrations in the middle of the South China Sea (SCS) from 1997-2007.
